HADRONIC PRODUCTION OF S-WAVE AND P-WAVE STATES OF (B)OVER-BAR-C-QUARKONIUM

In the leading O(alpha(s)(4)) order of the perturbative QCD, the hadro nic production cross-sections of S- and P-waves states of B-c meson ar e calculated. The results for the S-wave levels are compared with the values given in other papers as well as in the model of the b quark fr agmentation into B-c. In the given order, the cross-sections of the ha dronic production of the P-wave states are calculated for the first ti me. Their contribution into the B-c meson production is less than 10%. There is a strong difference between the predictions of the fragmenta tion model and the exact perturbative calculations. These differences are discussed in details for the differential distributions over vario us kinematical quantities.
